Incorrect rules interaction with ninjutsu
I am aware of the nuance combo with the ninjutsu ability and attacking creatures with first strike where you let the first strike combat damage be inflicted and then activate the ninjutsu from your hand before regular combat damage occurs and then the ninjutsu’d creature will then inflict combat damage in the “regular combat damage” portion of the damage step, this combo/interaction works correctly and as intended so long as there are no other attacking creatures WITHOUT first strike, if there are other creatures that would deal damage during the “regular” damage step then the ninjutsu creature will not inflict its damage like it would before.
Specific Example: I attack with just a Triumphant Adventurer which has first strike during my turn -> opponent does not block it -> it deals damage in the “first strike” portion of the damage step -> the game pauses to allow for any possible interactions (like ninjutsu or other instant speed abilities) -> I activate the ninjutsu of Biting-Palm Ninja and it enters the battlefield tapped and attacking -> the game then moves to the “regular” damage step and the Biting-Palm Ninja I just put into play will hit the opponent.
However, if you repeat the above steps except you attack with the Triumphant adventurer AND another creature WITHOUT first strike, you let the adventurer hit the opponent like before and again the game will pause for interactions so you activate the ninjutsu ability of Biting-Palm Ninja from your hand and return the adventurer to hand to put the ninja into play tapped and attacking, then the game will progress to “regular” damage as it did before but only the OTHER creature(s) without first strike will deal any combat damage, the Biting-Palm Ninja you just ninjutsu’d into play will not deal damage even though it did in the previous example with only the adventurer attacking.
Obviously this is an inconsistent and incorrect interaction with the rules and has cost me multiple games now due to that combat damage NOT being dealt.
I do not have screenshots or video to upload alongside this, but the above described situation should be detailed enough to recreate.
At the times I have encountered this bug there have been no other cards/effects/triggers on the stack or any abilities that would prevent any of the damage that should have been dealt, all occurrences have happened during best of 1 games in the alchemy queue, all on an iPad iOs.
I cannot confirm if this interaction works differently with other first strike attackers or other ninjutsu abilities as I have only tested this with the above named cards in the exact situation as described.
